Some abiotic, nonliving, factors that my plant depends on for survival are water, temperature, sunlight, and soil. The plants are dependent on biotic, living, factors because they need insects to pollinate the sprouts in order to grow a bean. Other biotic factors that affect the plants are diseases, predators, and other organisms.
I know my plants are engaged in competition because there are other plants growing in the same planter as the beans. Each of the plants are competing for sunlight and food.
"Winners" and "losers" are determined in the struggle for sunlight and food by which ever plant is bigger and germinates faster. Another factor would be if the plant is living or if it dies. Sometimes, it is complicated to determine who the "winner" and "loser" are because there could be more than one plant living in the designated area.
Another type of interaction, besides competition, that our plants are involved in is predation. Predation occurs when one organism eats another. The plants need to try and fight off the other bugs and organisms that are trying to eat them before they die completely.
Some evidence in the garden showing that succession (or something like it) is occurring in the garden ecosystem is the fact that there are organisms growing and living there. It is more like secondary succession because the garden has been there for a couple years and it previously had soil there.
